RSpec Rails 2.3

Rails-3

rspec-rails-2 supports rails-3.0.0 and later. For earlier versions of Rails,
you need rspec-rails-1.3.

Install

gem install rspec-rails

This installs the following gems:

rspec
rspec-core
rspec-expectations
rspec-mocks
rspec-rails

Configure

Add rspec-rails to the :test and :development groups in the Gemfile:

group :test, :development do
gem "rspec-rails", "~> 2.0.1"
end

It needs to be in the :development group to expose generators and rake tasks
without having to type RAILS_ENV=test.

Now you can run:

script/rails generate rspec:install

This adds the spec directory and some skeleton files, including a .rspec
file.

Webrat and Capybara

You can choose between webrat or capybara for simulating a browser, automating
a browser, or setting expectations using the matchers they supply. Just add
your preference to the Gemfile:

gem "webrat"
gem "capybara"

Note that Capybara matchers are not available in view or helper specs.

Issues

The documentation for rspec-rails is a work in progress. We'll be adding
Cucumber features over time, and clarifying existing ones. If you have
specific features you'd like to see added, find the existing documentation
incomplete or confusing, or, better yet, wish to write a missing Cucumber
feature yourself, please submit an
issue or a pull
request.
